. Be it known that I, AUeUsTUs D. FOU- oAR'r, a citizen ofthe United States, and a resident of Muncy, in the county of Lycoming and State of Pennsylvania, havermade certain new and useful -Improvements ink Elastic-Tire Wheels, of which the following is a specification. l

My invention is an improvement in 4means for securing pneumatic and solid-rubber f tires to the rims of wheels, particularly such as are intended for use on automobiles, bicycles, and traction engines.

The means I em lof)T enable the elastic tire to be readily app ied or detached' and yet holds the same securely.

The details of construction, arrangement and combination of l'parts are as hereinafter now to be described for securin described, and illustrated in the accompanying drawing, in whichf l Figure 1 is a viewin side elevation and partl in section of, al portion of. a vehicle whee and pneumatic At1re secured together .bymy improved meansa Fig. 2 is .an enlarged cross section of lthe Wheel' rim, the

" elastic tire, and the means for connecting them. Fig. 3 is a perspective view of a portion of the clencher, or clamping ring, constituting the\main feature of m invention.

A indicates the thick outer rub er tube of a` pneumatic tire and A the inilatable tube commonly employed therewith.

C is a so-called locking-ring, which may be of any suitable construction and is applied in the usual Way between the inner edges of the tube A. e

My invention is embodied in the -means the elastic tire tothe rim or felly of a ve icle wheel. An exteriorly threaded ring 1 having a flange lvononefedge, extends around', and-is securedto, :the wooden or Bf and upon it is` applied theclenchen or clamping.. ring, that secures the elastic. tire thereto. y.This ring' is;` formed in two parts designated, re-

spectively,by numerals Zand 3'. It will bek [understood that both, partsfare 'of annular '.form, and, in practice, extend completely around the rim B, and; thethreaded ring 1' l The part? is the broader o1. wider, and its in- `ner side is, screw-#threaded whereby it is Y gada tedto be screwedupon the ring 1 or on the elly or Wheel Theparts 2, 3, are provided with shouldered portions which are screw-threaded, as indicated at 4, Fig. 3, whereby they are adapted to be detachablyT connected, as shown 'in Fig. 2. Each of the parts 2, 3, is provided vwith an outwardly projecting inturned flange 5, which constitutes practically an annular hook adapted to clasp over and engage the beads a., which are formed on the edges of the outer tube A, see Fig. 2. -It is apparent that when the part 2 shall have been screwed upon the threaded rim-ring 1i) the other part 3 of the clencher 65 ring may e attached thereto by rotating it so as to engage the screw threads 4. In Fig. 3 Ishow a ring threaded on the inner side so it may be screwed directly on the wheel rim B..

It will be understood that the threads on the parts 1, 2, 3, and 4 are right and left. The threads may extend entirely around the Acircumference of the wheel, or may be single,

double or sectional threads,the double thread startin at `opposite points of the circumference o the wheel thereby facilitating the putting on or taking oif of the tire or rim.

It W1l1 be further understood that the detachable part 3 ofthe clencher ring is preferably on t on theinside. A screw 6, see Figs. 1 and 2, o ma be inserted through the wooden rim B an' the clencher sections 1 and 2, for securing the'parts together, so that there shall be one `on the other or of part 1 on the rim. By the meansdescribed an no movement o elastic tire is held securely on the wheel rim B, but may be readily detached as occasion re uircs.`

n order to prevent adhesion and undue `frictlon between the clencher-ring section 3 and the adjacent bead a of the elastic tire, I apply a protective sheathing 8, constructed o sheet metal or thin sheet ber, which in practice extends enti-rely around the wheel.

While my invention is shown in Figs. 1 and 2 as applied to the so-called clencher type of pneumatic tires it is equally applicable to tires ofthe Dun op type, in which the bases,

or inner edges) of the thick tube are formed with annularr eads wired to retain them inw shape, the beads themselves having a lateral o exterior projection, or being perfectly flat, as

the case may be.

It will be understood that vthe clencherilo' ring and the rim or ring that intervenesit and the vwooden rim or felly of the wheel are made of metal or a combination of meta s.

The combination, with an elastic tire, and

a wheel rim, of a clencher rin formed of screw-threaded parts, one -of w `ch is also e outside of the wheel, but may be 8O screw threaded on ite inner side, an annular flange 3a which abuts the opposite side'of the.

metal ring secured to said rim and which is metal ring 1, and also overlaps the said Wheel lo y threaded exteriorly and thus adapted for de rim, substantially as described.
